Description

Introduction

Haanssluis, a sluice-lock, located between the Schildmeer and the Haansvaart which cuts through the Schildjerpolder situated to the north of Hellum. The Haanssluis was built in 1866-1867 simultaneously with the construction of the Haansvaart on the orders of farmer Hindrik de Haan (1827-1899) who was both owner of the Haansvaart and of the Haanssluis; the Haansvaart connected his farmhouse with the Schildmeer. The Haanssluis was rebuilt in 1909 by Johannes de Haan (1875-1963) son of Hindrik, on the same site, whereby most likely parts of the old Haanssluis were preserved. Initially, fertile soil was transported from artificial dwelling mounds and terpen across the Haansvaart, later also peat and agricultural products. After the Second World War the sluice and waterway fell into disuse and maintenance stagnated. The Haanssluis functioned as a sluice-lock between the Haansvaart and the Schildmeer which formed part of the boezem of Duurswold. Under "normal" circumstances the Haansvaart was also boezem water of Duurswold. During high water in the boezem the Haanssluis was closed as a lock in order to keep back high water from the Schildmeer c.q. "keep it out", but under normal circumstances the sluice was open. For the purposes of (continuity of) navigation, at times when the sluice had to be closed as a lock, the Haanssluis had to be constructed as a sluice-lock.

Description

The chamber length of the SLUICE-LOCK, named Haanssluis, measures 24 metres, the width 4.20 metres. The Haanssluis has two simple masonry, brick sluice heads whereby the top layer is constructed as a rolling course. At the corners and above the natural stone strike-posts natural stone coping stones have been placed. A curved steel profile protects the vertical edges of the heads at the ends of the sluice and at the sluice chamber. It is assumed that the entire object has a timber pile foundation and that the sluice heads have timber floors with similar sill stones. The walls of the lock chamber consist of vertically masoned trough vault construction or wulf walls in brick (clinkers) between iron or steel beams. The two sluice heads are each provided with a set of timber pointed gates. The western gates have a levelling shutter which is connected with a hinge rod with a gearbox placed above it. A walkway with a simple iron railing has been fitted on the gates. In the outer sluice head a memorial stone is set in on either side of the chamber. The eastern stone contains the text: "BUILT BY H. DE HAAN. 1866." The western stone contains the text: "REBUILT BY JOHS DE HAAN AND ST DE HAAN BOUKEMA. 1909."

Valuation

The Haanssluis, SLUICE-LOCK, located near Hellum between the Schildmeer and the Haansvaart, built in 1866-1867 by Hindrik de Haan and rebuilt in 1909 by his son Johannes on the same site, represents a matter of general interest on the basis of:

- its age;

- its building historical significance as expressed amongst other things in the application of vertically masoned trough vaulting which is considered rare;

- the reasonable degree of integrity of the object;

- its significance for the history of water management, namely a sluice-lock constructed as a lock which came into being thanks to private initiative and in combination with the construction of the Haansvaart;

- the landscape and historical appreciation value and significance contained in and around the Haanssluis, with Haansvaart and Schildmeer.
